       7. The transformer containment bag of  claim 1  wherein the reinforcing band is positioned around a center height location of the outer bag and lifting loop. 
     
     
       8. The transformer containment bag of  claim 1  further comprising:
 a plurality of reinforcing bands, the reinforcing bands including an upper reinforcing band secured around the top end of the outer bag and lifting loop, a center reinforcing band secured around a center height location of the outer bag and lifting loop, and a lower reinforcing band secured around the bottom of the outer bag and the lifting loop. 
 
     
     
       9. The transformer containment bag of  claim 3  further comprising:
 a plurality of reinforcing bands, the reinforcing bands including an upper reinforcing band secured around the top end of the outer bag and lifting loop, a center reinforcing band secured around a center height location of the outer bag and lifting loop, and a lower reinforcing band secured around the bottom of the outer bag and the lifting loop. 
 
     
     
       10. A transformer containment bag comprising:
 a leak-tight bag of multi-wall construction, with an open top, a first multi-layer liquid-barrier side structure, and a second multi-layer liquid-barrier bottom structure at the bottom of the side structure; 
 the first multi-layer liquid-barrier side structure having an outer puncture-resistant liquid-barrier fabric layer and a tear-resistant liquid-impervious liner secured inside the outer layer, the outer layer and the liner having open tops secured together to establish an open top for the bag; 
 the second multi-layer liquid-barrier bottom structure having an outer puncture-resistant liquid-barrier fabric layer with an inner cushioning oil-absorbent mat, and a tear-resistant liquid-impervious liner secured inside the outer layer; 
 a high strength lifting loop secured longitudinally along the length of the bag side structure and positionable above the open top of the bag to enable grabbing the lifting loop and lifting the bag from above; 
 a high strength reinforcing band secured around the bag side structure and lifting loop; and 
 a duffel top secured to the top of the bag side structure and openable for exposing the open top of the bag from above;
